5.3 Checking opening and closing intervals
If the gripper does not achieve the opening and closing times
specified in our latest catalog, check the following points:
• Are the throttle valve connections at the sviwel unit opened as
far as possible?
The movement must be carried out without
bumping and bouncing.
• Do the compressed air lines to the swivel unit have a sufficient
inner diameter regarding the compressed air consumption?
• Are the compressed air lines between the swivel unit and the
valve as short as possible?
• Is the flow rate of the directional control valve sufficient for the
swivel unit's compressed air consumption?
If the movement times in the application determined by SCHUNK
are not reached despite optimal compressed air connections,
SCHUNK recommends using quick exhaust valves directly at the
swivel unit.
5.4 Adjusting the swivel angle
By inserting or removing balls in/from a ball guide rail, the range of
the swivel angle can be roughly adjusted between 0° and 180° or
0° and 90°.
Adjust the end position dampers (shock absorbers for S-variant or
elastomer for E-variant) in order to fine tune the end positions of
the swivel angle range.
